I'm not sure if you read the article but someone in the comments summarized the top pressure skaters (to no surprise really) were:
M Backlund
J Gaudreau
S Monahan
M Frolik
S Bennett
Doesn't surprise me, Monahan rarely loses puck battles, Gaudreau has good hands and loses possession from dumb passes not battles, Backs and Fro both are smart board players and Bennett is relentless.
When your bottom 6 includes an over-the-hill Stajan, a trash Brouwer, a completely useless Lazar and Hathaway and the top 6 includes an over-rated Ferland it doesn't surprise me. Our 4th line literally had the puck for 15% of the time, they were always in their zone because they couldn't do f*** all.
Ignoring the players though, Gulutzan's system was wayyyy too passive. Playing games to get to OT, playing hockey to minimize mistakes rather than take risks (which is the opposite of what Peters employs) and other soft tactics is why we were pushed around so easily, it's why our games were for the most part boring to watch, it's why we couldn't score goals. This was a huge reason why the Flames sucked so much last year, horrible coaching tactics. Peters doesn't employ these tactics at all, he preaches players taking risks and doesn't like to play mistake free hockey because it kills creativity which is why it neutered Bennett so much, he took too many penalties because he played too aggressively then was in the dog house because of it.
